Heat Recovery Steam Generator

  •  Steam flow 10,000 to 150,000 lb/hr 
  •  Steam pressures up to 2,300 psig 
  •  Steam temperatures to 1,050°F 
  •  Available to less than 2 ppm NOx 

Cleaver-Brooks Slant series natural circulation heat recovery steam generators feature the Slant model and VC (Vertical Drum Cross Flow) model. Both models are tailored to applications  with gas-side inlet temperature less than 1,700°F. 


The Slant model offers an integral steam and water (mud) drum positioned diagonally which maximizes the amount of heating surface for a given shipping profile creating a compact design for efficient heat recovery.

The VC model is a drum-over-drum design well suited for higher steam pressure applications,  integrated CO/SCR (selective catalytic reduction) systems, and horizontal exhaust flow arrangements.

  • Cold casing design with 300 and 400 series stainless steel or A-242/A-588 inner liners, depending on the gas-side temperature and service
  • Multiple gas flow options conform to space restrictions and minimize cost
  • Unheated downcomers, completely external to the boiler casing
  • Single-pass design for lower gas-side pressure drop
  • Multiple casing options including membrane wall construction
  • Ease of access to tubes for inspection and maintenance
  • Compact design results in low installation costs
  • Can accommodate selective catalytic reduction (SCR) and CO catalyst
